Worldwide, the United States is home to more immigrants than any other country, and more than the next four countries—Germany, Saudi Arabia, the United Kingdom, and France—combined, according to the most recent UN Population Division data. While the United States represented about 4 percent of the total global population in 2024, 17 percent of all international migrants resided in the United States.
The size, though not the share, of the U.S. immigrant population is at a record high. Immigration has been an important contributor to U.S. population growth, which has slowed in the past decade due to falling birth rates. Amid this demographic slowing, immigration accounted for the entire growth of the total U.S. population between 2022 and 2023—the first time this has happened since census data collection on nativity began in 1850.
There were 47.8 million immigrants residing in the United States as of 2023, according to the latest American Community Survey (ACS) from the U.S. Census Bureau. Of them, nearly three-quarters were in the country legally as naturalized citizens, legal permanent residents (LPRs, also known as green-card holders), or holders of temporary visas.
